Strange occurrences with my streaming accounts

I know this is really minor, but it is bugging me a great deal because it is still happening.  I have been noticing for the past several months that there are odd things going on in my streaming accounts and I am wondering if it is just mine.  You know how there is a red line that runs underneath of an episode that you have already viewed?  I keep finding these on shows that I have no memory of watching.  I have even tried to view a few of these episodes from the beginning to see if it refreshes my memory.  Nope.  These are shows that I have not watched.

 My first reaction was to change all of my passwords.  Although, I live alone and have never given anyone any of my passwords to Netflix, Hulu, or Amazon.  I still keep coming across shows that look like I have already seen a few episodes when I know I have not.  And my passwords are quite difficult and different for all three of those services, and the likelihood that anyone has cracked even one is very small.  All three?  Impossible.

The only thing that I have come up with as a possible reason for this is that I fell asleep while watching some program and it automatically advanced into the next available show without me clicking on it.  I don’t know if that is possible, but it is the only viable reason that I have come up with so far.

And I have a habit of always adding a series to the “my list” section because I will often watch a few episodes of something, then need a change and watch something else, but usually returning to watch the next episode from where I had left off a few nights before.  

For example, my friend strongly recommended that I watch the Vikings series on Netflix.  He kept pushing me to do it because he wanted to talk to me about the various episodes.  I actually had to upgrade my plan to another level to give me access to that series, but I did so because he was so adamant that I would enjoy it.  There are six seasons and up to 20 episodes per season, so this is going to take me some time to complete.

Well, I did enjoy it in the beginning, but this isn’t really a show that I can binge multiple episodes at a time because it is so terribly violent.  Really, really violent.  I can usually only watch one per evening, then I need to switch to something light so that I can fall asleep without dreaming of bloody killings.  I had no idea that the Vikings were that bloodthirsty of a people.  And the fastest way for me to return to a series like this that I am watching sporadically is to go to the “my list” tab.  Otherwise, several new things have popped up and I can’t find the program I am looking for without a lot of scrolling and hunting.

And then I began to notice that when there were shows where a few episodes had been watched with no memory of them, I had not clicked the “my list” option.  I have been doing that for years, so that was a telltale sign that it really wasn’t me watching these shows.

I know this isn’t a big deal and I can just begin at the first episode if it actually IS something that I want to watch, so there is no harm done.  Well, other than me thinking I am losing my mind a bit.  And at my age, I already do things like enter a room and forget what I went there to get and have to return to where I started to realize what I was actually looking for.  I know that is quite common and it doesn’t happen to me all that often.  

I saw it happen with my mom and she was as sharp as could be.  And mine seems to occur most often when I am listening to an Audible book as I am working and getting engrossed in the storyline.  The thought that I may possibly have watched multiple episodes of a show and can’t remember a single scene is very worrisome.  I watched my ex husband’s mom develop Alzheimer’s and it was horrible for all of us.  I think the fear of that happening to me is occasionally in the very back of my mind.

I haven’t yet tested out the theory that I fell asleep and a new show started playing automatically. The only other answer is that I have a ghost living with me, although we don’t always share the same taste in movies.

Has anyone else had this happen to them with any of their streaming services?
